How do you know you’re getting diagnostic results from your probe?
Does you service provider test them?
How do they test them?
Probably with a tissue equivalent phantom!
Tissue equivalent phantom will test:
Axial resolution – this is mainly affected by the speed of ultrasound or the pulse width.
Lateral resolution – this is mainly affected by the beam width and the processing within the machine.
It will not successfully test:
Dropout – IF it is bad enough (it is not possible to see drop out in a cardiac probe as all elements fire together)
Cable breaks
Dead or weak elements
Individual elements shorting
Shorts in cables
Lenses delaminating
